The incidence of 0 degrees is the first aspect worth mentioning about this product. In addition to this, the visible infrared is transmitted, and the items also reflects the near infrared spectrum, which is typically found in Tungsten light sources. The products in the hot mirror series are therefore capable of removing much of the energy that causes heating in a lighting system. In addition, they can also be used as alternatives to KG1 filters, especially in situations where the light focuses near the filter, providing a cracking risk.
The products in this series reflect heat, rather than absorbing it, while the custom hot mirrors also come with a sharper cut off between the Visible and the IR, as they have a dielectric coating that users can control. Knight Optical, the manufacturer, also produces stock large sheets of 600mm, while custom units are available for visible applications.
